Hanging around this site means one thing ONLY: you don't know what to do with yourself. Hit your books instead of goofing off!.

I think its The Tower Bridge

A MILLION !

DOCTOR WHOOO!!!

what the h**l!!!^^^^

I actually need some help!!!

I need to know.

THATS NOT MATH!!!!!

I am asuming you MEANT  x^2 + 36x - 10

You can use the quadratic equation to fin the values of 'x'

(-36 +- sqrt(36^2- (-40)) )/2 =  .2756 , -36.2757

Then factored it would look like this:

(x - .2756)(x+36.2757) = 0

I think you didn't copy it right. Look carefully, if it is in a book. If you copied it from the blackboard, then you made mistake in copying it.

I think Melody misread the question.   The question REALLY asks how long before the wound is 90% smaller.

There are two ways to answer this, depending on what you are learning these days.....if the wound shrinks a contant amount of the original each day (5%) then we need to find how many days to shrink 90%

90/5 = 18 days.

If the wound shrinks 5% of the wound area on THAT day, a different answer will result: As per Melody's method

0.1 = 1(0.95)^n

log0.1/log0.95 = n = 44.89 days        (I think)

what is the factor of x^2+36-10 im getting confused

=(sqrt(26)-ix) (sqrt(26)+ix) (These are complex factors)

Is that all that was given? I don't understand what is being asked.

Not clear!! Write it clearly, especially your power "^" signs.

Solve for x:
e^2 x^2-2 = 4

Add 2 to both sides:
e^2 x^2 = 6

Divide both sides by e^2:
x^2 = 6/e^2

Take the square root of both sides:
Answer: | 
| x = sqrt(6)/e               or x = -sqrt(6)/e

.4 * 55,416,666

Well, 90 degrees is 1/4 of a circle (360 degrees) ...so th area will be 1/4 of the total area of the circle....

Area = pi r^2  = pi (5)^2       the area of the segment will be 1/4 of this total right.....?  Can you figure it out now?

What is the VOLUME and AREA of a hemisphere? They must be in your book.Just look them up.

  MOLARITYis the number of MOLES per LITER of SOLUTION.  You have the two numbers necessary to calculate this value......DO you need more help?

Look up the formula in your Chemistry book. It is all there if you look carefully.

what is 40% of 55,416,666=40/100 X 55,416,666=22,166,666.4
